Instructions for using Kali

Kali is a program for drawing symmetric (repeating) patterns. You have your choice of any of the 17 wallpaper patterns or 7 frieze patterns.

These instructions are for using the Kali program as installed on the Sun computers in the CSUSB Math Dept. For a Web version or a (free, downloadable) Macintosh version, see the Geometry Center ( http://www.geom.umn.edu/java/Kali/).

Instructions

1. Start Kali by double-clicking the Kali icon or typing kali in a command tool window.
2. Choose your pattern type. For a wallpaper pattern, click on one of the 17 wallpaper groups. For a frieze pattern, hold down the mouse on the words Wallpaper Groups, and release on Frieze Groups. Then click on one of the frieze groups.
3. Draw a design. You can use only line segments to make your design. To start a chain of line segments, click in the drawing window. Click in another place for the endpoint. Continue clicking in different places for more line segments in the chain. To end the chain, click with the middle mouse button.
4. Editing your design. To select a line segment, click it with the right mouse button. Then you can delete it by clicking the middle mouse button, or move an endpoint by dragging the endpoint with the left mouse button.
5. Saving your design. To save in a format that you can work on again, click the Save button; type a name for your design if it doesn't already have one, then click Ready.
6. Printing your design. This is a two-step process. First click Print To; type a name ending with ".ps" in the window, then click Ready. (This saves your design in Postscript format.) Second, type "gspr blah.ps" (replacing blah.ps with the name you chose, and not typing the quotation marks) in a Command Tool window. Your design should come out on the printer in the lab.
